Detailed Description
Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
As shown in fig. 1 to 4, it is a schematic structural diagram of a high reliability door lock and an electrical device provided by the present invention. The electrical apparatus includes a door panel 10, and a highly reliable door lock 20 mounted on the door panel 10. The electrical equipment can be a washing machine, a refrigerator, a freezer and other equipment with an opening and closing door. In addition, it is conceivable that the electrical apparatus further includes other functional modules, such as a functional frame, an electrical connection component, various electrical apparatuses, and the like, which are well known to those skilled in the art and will not be described herein again.
The door panel 10 may be a component of an electrical apparatus, but in the present embodiment, the door panel 10 is only partially shown for explaining the structure of the high reliability door lock 20 and the installation structure between the high reliability door lock 20 and the door panel 10. The door panel 10 may be made of a metal plate and is provided with a mounting hole 11. The thickness of the metal plate can be set according to the actual requirements and will not be described in detail here. The shape of the mounting hole 11 can be designed according to actual needs, and in this embodiment, the mounting hole 11 is a rectangular hole, and the size of the rectangular hole is also designed according to actual needs, such as the size of the high-reliability door lock 20.
The high reliability door lock 20 includes a housing 21, a mounting portion 22 disposed on the housing 21, and an abutting member 23 disposed in the housing 21. It is contemplated that the high reliability door lock 20 may also include other functional modules, such as a door hook mechanism, an electric control device, etc., which are known in the art and will not be described herein. The housing 21 includes an upper housing 211, and a lower housing 212 coupled to the upper housing 211. The upper housing 211 and the lower housing 212 may be connected by a fastener or by a snap-fit connection. In this embodiment, the upper housing 211 and the lower housing 212 are connected by a snap-fit manner. The upper housing 211 and the lower housing 212 form a cavity for receiving various functional components, including the abutting component 23. The functional components housed in the housing 21 may include, for example, a sensor or the like, which transmits information about the opening or closing of the door to a processor of the electrical device for subsequent operations, such as starting the operation of the motor.
The mounting portion 22 includes a supporting member 221, a connecting neck 222 connecting the supporting member 221 and the upper housing 211, a first locking edge 223 disposed on one side of the supporting member 221, and a second locking edge 224 disposed on the other side of the supporting member 221.
The shape of the buckling body 221 is the same as that of the mounting hole 11, that is, the cross section is rectangular. Meanwhile, in order to insert the fastening body 221 into the mounting hole 11 and to sandwich the door panel 10 between the mounting portion 22 and the housing 21, the length of the fastening body 221 is greater than the length of the mounting hole 11, and the width of the fastening body 221 is equal to or less than the width of the mounting hole 11. In addition, the abutting-buckling body 211 is a hollow structure, so that the door hook can be inserted into and hooked with a latch hook mechanism of the door lock.
The connecting neck 222 is inserted into the mounting hole 11, in order to achieve the fixing between the connecting neck 222 and the door panel 10, even if the connecting neck 222 and the mounting hole 11 are fixed to each other, the length of the connecting neck 222 is smaller than the length of the mounting hole 11, but the width of the connecting neck 222 is equal to or smaller than the width of the mounting hole 11, preferably, the width of the connecting neck 222 is equal to the width of the mounting hole 11, so that when the position relationship between the connecting neck 222 and the mounting hole 11 is fixed in the length direction of the connecting neck 222, the position relationship between the connecting neck 222 and the mounting hole 11 can be fixed. How to fix the positional relationship between the connecting neck 222 and the mounting hole 11 along the length direction of the connecting neck 222 will be described below in conjunction with the abutting assembly 23.
The first and second locking edges 223 and 224 are respectively disposed on two sides of the fastening body 221 along the length direction of the connecting neck 222. The first locking edge 223 extends from a side wall of the upper housing 211, thereby forming a cantilever. The first catching edge 223 in the cantilever form may be obliquely inserted into the mounting hole 11 of the door panel 10, as shown in fig. 4. The first locking edge 223 is spaced apart from the upper housing 211, and a minimum distance between the first locking edge 223 and the upper housing 211 is equal to a thickness of the door panel 10, so that the door panel 10 can be clamped between the first locking edge 223 and the upper housing 211. The second locking edge 224 also extends from the sidewall of the upper housing 211 and is disposed at the opposite side of the buckling body 221. The second locking edge 224 is spaced from the upper housing 211, that is, the minimum distance between the second locking edge 224 and the upper housing 211 is also equal to the thickness of the door panel 10, so that the door panel 10 is clamped in the gap formed between the second locking edge 224 and the upper housing 211 during installation. Of course, the maximum distance between the first and second locking edges 223 and 224 should be greater than the length of the mounting hole 11, so that the maximum cross-sectional area of the fastening body 221 is greater than the area of the mounting hole 11, so as to lock the door panel 10 between the first and second locking edges 223 and 224 and the upper housing 211. The first locking edge 223 further includes a yielding space 225, the yielding space 225 is used for accommodating the end portions of the abutting member 234 and the elastic abutting head 235, that is, when the upper shell 211 and the lower shell 212 are connected together, the end portions of the abutting member 234 and the elastic abutting head 235 are inserted into the yielding space 235. Due to the small thickness of the door panel 10, in order to ensure that the door panel 10 can abut against the elastic abutting head 235, the door panel 10 is prevented from being inserted between the elastic abutting head 235 and the first locking edge 223, thereby causing the fixing failure of the door panel 10 and the high-reliability door lock 20.
The abutting assembly 23 includes an avoiding groove 231 disposed on the upper housing 211, an assembling groove 232 disposed on the upper housing 211, a pull rod 233 inserted into the assembling groove 232, an abutting member 234 disposed on the pull rod 233, an elastic abutting head 235 disposed on the lower housing 212, and a restoring elastic member 236 disposed between the pull rod 233 and the assembling groove 232. The avoiding groove 231 is formed on the upper housing 211 and is close to one side of the abutting-buckling body 221, specifically, one side of the abutting-buckling body is close to the first clamping edge 223. The depth of the avoiding groove 231 is smaller than the total thickness of the elastic abutting head 235 and the abutting piece 234 and is larger than the thickness of the elastic abutting head 235, so that when the abutting piece 234 is located between the elastic abutting head 235 and the avoiding groove 231, the elastic abutting head 235 is exposed or extends out of the avoiding groove 231, at the moment, the length formed by the elastic abutting head 235 and the connecting neck 222 is equal to the length of the mounting hole 11, so that when the mounting hole 11 of the door panel 10 is sleeved on the elastic abutting head 235 and the connecting neck 222, the length direction of the mounting hole 11 is limited by the length of the elastic abutting head 235 and the length of the connecting neck 222, the width direction of the mounting hole 11 is limited by the width of the connecting neck 222, and the door panel 10 is clamped between the first clamping edge 223 and the second clamping edge 224 and the upper shell 211, so that the relative position of the door panel 10 and the high-reliability door lock 20 can be limited in the three-dimensional direction, and the purpose of fixed installation is achieved. When the door panel 10 is detached, the abutting member 234 is pulled out from between the elastic abutting head 235 and the avoiding groove 231, that is, the abutting member 234 is hidden in the assembling groove 232 and is moved out from the avoiding groove 231, so that when the door panel 10 is pressed toward the second clamping edge 224, the elastic abutting head 235 can be pressed into the avoiding groove 231 under the action of external force, for example, under the pressing of the side wall of the mounting hole 11 of the door panel 10, and meanwhile, because the length of the connecting neck 222 is smaller than that of the mounting hole 11, when the door panel 10 is tilted again, the mounting portion 22 can be separated from the clamping connection with the mounting hole 11 of the door panel 10.
The assembling groove 232 is disposed in the upper housing 211, and extends in a direction perpendicular to the depth direction of the avoiding groove 231. The assembling groove 232 is used for disposing the pull rod 233, and in order to dispose the restoring elastic member 236, one end of the assembling groove 232 is closed and the other end is opened. The pulling bar 233 is inserted from one end of the assembling groove 232 and abuts against the other end of the assembling groove 232. Therefore, the structure and size of the assembling groove 232 should be designed according to the structure and size of the drawbar 233, and in this embodiment, the drawbar 233 is a plate-shaped structure, so the assembling groove 232 is a groove shape. The assembling groove 232 and the avoiding groove 231 are disposed to cross each other, so that the avoiding groove 231 has a certain depth, and the avoiding groove 231 has a certain depth even though the pull rod 233 is inserted.
The pull rod 233 is inserted into the assembly groove 232, and is used for enabling the abutting piece 234 to be inserted between the elastic abutting head 235 and the avoiding groove 231 or to be drawn out from between the elastic abutting head 235 and the avoiding groove 231 when the pull rod is in a free state or is pressed. It is conceivable that the pull rod 233 is further provided with a number of stopper members to prevent it from falling out or being pulled out when it is in a free state in order to restrict the position of the pull rod 233. In addition, since the upper housing 211 and the lower housing 212 are fastened together, the assembly groove 232 forms a closed space when the upper and lower housings 211, 212 are assembled together, so that the pull rod 233 is received in the assembly groove 232 and can move only within a certain range, i.e., only along the length direction thereof.
The abutting member 234 is provided on the pull rod 233 to be reciprocatable with the pull rod 233. The size of the abutting member 234 in the depth direction of the avoiding groove 231 should be strictly limited, that is, when the abutting member 234 is inserted between the elastic abutting head 235 and the avoiding groove 231, the overall length formed by the abutting member 234, the elastic abutting head 235 and the connecting neck 222 is equivalent to the length of the mounting hole 11, so as to limit the position of the mounting hole 11 in the length direction thereof. Of course, when the door panel 10 is pressed toward the second locking edge 224 after the abutting member 234 is drawn out from between the elastic abutting head 235 and the avoiding groove 231, the elastic abutting head 235 can be pressed into the avoiding groove 231 under an external force, such as the pressing of the side wall of the installation hole 11 of the door panel 10. Therefore, the position of the abutting member 234 on the pull rod 233 should be such that when the pull rod 233 is in a free state, the abutting member 234 is inserted between the elastic abutting head 235 and the escape groove 231, and when the pull rod 233 is pulled out or pressed, the abutting member 234 is pulled out from between the elastic abutting head 235 and the escape groove 231.
The elastic abutting head 235 is disposed on the lower housing 212, i.e., extends from the lower housing 212 toward the upper housing 211, and when the upper and lower housings 211, 212 are assembled together, the elastic abutting head 235 is inserted into the avoiding groove 231. The elastic abutting head 235 has a certain elasticity because the elastic abutting head 235 extends from the lower housing 212 to form a cantilever. As mentioned above, the size of the elastic abutting head 235 should be the same as the size of the abutting piece 234, the size in the depth direction of the avoiding groove 231 should be strictly limited, and the specific size design thereof should be the same as the size design of the abutting piece 234, and will not be described herein again.
The restoring elastic member 236 is disposed between the pull rod 233 and the assembling groove 231, which may be disposed on either side of the abutting member 234, such as left or right, so as to restore to an original position by the restoring elastic member 236 after the pull rod 233 is pressed or pulled.
When mounting, the pull rod 233 is firstly pressed, the abutting piece 234 is drawn out from between the elastic abutting head 235 and the escape groove 231, and then the mounting portion 22 is obliquely arranged with respect to the door panel 10 to be inserted into the mounting hole 11 of the door panel 10. The door panel 10 is pressed against the elastic abutting head 235 to be pressed into the avoiding groove 231, at this time, the door panel 10 can be sleeved on the connecting neck 222, at this time, the door panel 10 can be inserted between the second clamping edge 224 and the upper shell 211 by pulling the door panel 10, then the pressing of the pull rod 233 is released, and the abutting piece 234 is inserted between the elastic abutting head 235 and the avoiding groove 231, so that the size of the elastic abutting head 235, the abutting piece 234 and the connecting neck 222 in the length direction is equivalent to the length of the mounting hole 11 of the door panel 10, and the position relationship of the door panel 10 and the high-reliability door lock 20 in the length direction along the mounting hole 11 is limited. When the high-reliability door lock 20 needs to be disassembled, the high-reliability door lock 20 can be disassembled from the door panel 10 according to the reverse process operation of the installation process.
Compared with the prior art, the utility model provides a high reliability lock is through setting up on the last casing 211 of casing 10 dodge groove 231 set up elasticity on the lower casing 212 and support top 235 to should dodge groove 231 and elasticity and support and set up between top 235 and support piece 234. When the high reliability door lock 20 is installed on the door panel 10, a user presses or pulls the abutting member 234, so that the abutting member 234 is pulled out from between the elastic abutting head 235 and the avoiding groove 231, so that when the installation hole 11 of the door panel 10 presses the elastic abutting head 235, the elastic abutting head 235 retracts into the avoiding groove 231, and the size formed by the elastic abutting head 235 and the installation part 22 is reduced, so that the door panel 10 is easily sleeved into the installation part 22, then the abutting member 234 is released, the low abutting member 234 is inserted between the elastic abutting head 235 and the avoiding groove 231, and then the elastic abutting head 235 rigidly abuts against the side wall of the installation hole 11, thereby achieving the purpose of fixing the relative position between the high reliability door lock 20 and the door panel 10. When the door lock needs to be disassembled, the door lock can be disassembled from the door plate only by executing the actions in the opposite action flow. Therefore, the high-reliability door lock 20 can be installed on the door panel 10 without using a fastener, and the high-reliability door lock 20 can be safely and reliably installed on the door panel 10 due to the elastic abutting head 235.
